TiCl3

Titanium trichloride (TiCl₃) is a layered transition metal halide compound that exists as a crystalline solid with weak interlayer bonding. While not typically used as a structural engineering material itself, TiCl₃ is primarily encountered as a chemical intermediate in titanium metallurgy and as a precursor in advanced materials synthesis, particularly for producing titanium metal via the Kroll process and in catalyst formulations for polymerization reactions. Its layered crystal structure and relatively low exfoliation energy make it of emerging interest in materials research for potential applications in two-dimensional material engineering and nanocomposite development, though industrial deployment remains limited compared to titanium alloys and oxides.
